چکیده

This work shares purpose with new directions in the philosophy of intellectual property, where selfexpression and participation in the creation of culture are seen as key ingredients of human wellbeing and autonomy. A technical solution is explored that enables major labels and independent creators to publish music with equal reach to audiences, without the need for trusted third parties. The principal contribution is a buyer-seller protocol in the setting of untrusted service providers and a blockchain ledger. In the envisioned scenario, files are streamed from untrusted providers to end users. Encryption and watermarking, rather than obfuscation, are used to protect against and disincentivize piracy. Watermarking bit rate, storage and communication overheads, and encryption performance are key parameters. Subscription and ad-supported pricing models are discussed. Sammanfattning Detta arbete delar syfte med nya idéer inom immaterialrättsfilosofi, där yttrande och delaktighet i skapandet av kultur ses som nödvändiga ingredienser för mänskligt välbefinnande och självständighet. Rapporten utforskar en teknisk lösning som möjliggör för stora mediebolag och oberoende artister att publicera musik med samma åtkomst till publik, utan behov av betrodda tredjeparter. Det huvudsakliga bidraget är ett köpar-säljar-protokoll för en miljö med obetrodda service providers och en blockchain ledger. I det föreställda sceneriot skickas filer från obetrodda parter till slutanvändare. Kryptering och vattenmärkning, snarare än obfuskering, används för att skydda mot och avskräcka från piratkopiering. Vattenmärkningens bithastighet, lagringsoch kommunikations-behov, samt krypteringens prestanda är avgörande parametrar. Subscription och ad-supported som prismodeller diskuteras.
